Water-sensitive paper auxiliary photographing device and photographing method for mobile phone

Abstract

The invention discloses a water-sensitive paper auxiliary photographing device and photographing method for a mobile phone. A mobile phone clamping frame in the auxiliary photographing device is connected with a two-dimensional moving platform through a bolt structure, the two-dimensional moving platform is installed on a liftable stand column, the stand column, a control panel and a soft light box are installed on a base through a bottom plate, and a paper placing platform is installed in the base. When the water-sensitive paper is shot, the mobile phone is clamped and fixed firstly, and thenthe left-right position, the front-back position and the height of the mobile phone are adjusted, so that a camera of the mobile phone directly faces a water-sensitive paper shooting area in the basethrough the soft light box. After the water-sensitive paper is placed on the paper placing platform, a switch of the control panel is pressed down, and the device can automatically photograph the water-sensitive paper one by one. The device and the method can be widely applied to places such as field production and scientific experiments, so that the mobile phone can quickly take pictures of thewater-sensitive paper with high quality, the use is simple and convenient, and the production, manufacturing and maintenance costs are low.

Description

technical field [0001] The invention belongs to the technical field of auxiliary machinery for agricultural plant protection, in particular to a mechanical device for assisting photographing with water-sensitive paper for mobile phones. Background technique [0002] Agricultural water-sensitive paper is often used in fields, agricultural machinery laboratories and other environments to measure the droplet deposition distribution of different spray methods, to detect the spraying effect of equipment, and to evaluate the performance and operating parameters of spraying equipment. It has a wide range of uses . The principle of water-sensitive paper is to develop color after encountering a solution such as water, thereby forming a deposition pattern of sprayed droplets on the paper surface. A clear water-sensitive paper image is the premise and basis for obtaining data such as droplet density, particle diameter, and number of droplets, so a stable image acquisition method is pa...
